Description
Separating funnel, 1000 ml, pear-shaped and ungraduated, is designed for efficient liquid-liquid extractions and clean phase separations in routine laboratory practice. Made from borosilicate glass 3.3, it is fitted with a solid glass key stopcock featuring an NS 18,8/6 mm bore and a polyethylene stopper NS 29/32. The pear-shaped (BF) body aids formation of distinct interfaces and controlled release of the denser phase. Manufactured to ISO 4800 and supplied ungraduated, the funnel suits workflows where external volumetric measurement is preferred over onboard scale markings. Nominal volume is 1 l with a net weight of 0,454 kg; the article is delivered as a single piece. Chemical resistance and thermal stability of the borosilicate construction support repeated use in synthesis, sample work-up and analytical preparation. Offered by manufacturer Rettberg, this separating funnel pairs readily with standard ground-joint apparatus. The solid glass stopcock and PE stopper provide reliable sealing during mixing and settling stages of extraction procedures.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Separatory funnel, 1000 ml, conical, non-grad., glass plug size 18,8/6 mm,
What is this article?
Separatory funnel, 1000 ml, conical, non-grad., glass plug size 18,8/6 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
